Resin bond CBN grinding wheel for gear hob cutter

Resin bond CBN grinding wheel for gear hob cutter

This type of CBN grinding wheels are specially used for gear hob cutter grinding,
before grinding, we need to use Green silicon carbide grinding wheel dress it, to make sure it has good concentricity.
During grinding, if you find the CBN wheel you are using is a little bit hard, you should slow down the line speed from 40m/s to 30m/s.
The roughness and sharpness are the most important for the CBN wheels.
